Novell ZENworks Linux Management Linux Management 7 - ZLM7
Using random or repeating schedules involving GMT time that spans midnight, meaning a start time before midnight and an end time after midnight GMT, will not execute policies.
Fixed in Novell ZENworks 7.2 Linux Management DE edition.
Standard times schedules are not affected by this issue. Use standard times to enable the ability to span start and end times that include midnight.
